摘要
本文用 Brabender PLE331型流变仪研究了 PC/PA1010共混物的流变特性。结果表明:PA1010的加入,能明显降低 PC 的平衡扭矩(粘度),提高 PC 熔体的流动性,改善了 PC 的成型加工性能。当 PA1010用量较少时,基本保持了 PC 的流变特性,即共混物的粘度对温度很敏感,而剪切速率对粘度的影响则很小。
The theological properties of PC/PA1010 blends have been studied by me-ans of Brabender PLE 331 rheometer.It is discussed that the effect of shearrate,temperature and composition on the torque(apparent viscosity)of pc/PA1010 blends.The results showed that the torque obviously decreased as thecontent of PA1010 increased and the temperature rose.The shear rate hasa little effect on the torque.
